Helix pulcheila. Found at Ratham, and at Bersted, near Bognor. 
Limnaus trunculatus. Have found this shell more plentifully about here 
since my report in 1868, and have also found it at Lindfield. It has a 
habit of following the flow of water during floods, and often gets left high 
and dry in summer, but appears capable of sustaining life so long as a little 
moisture is left. 
Ancyclus fluviatilis. Common in our running streams. 
Physa fontinalis. Generally distributed, but not plentiful. 
Aplexus hypnorum. Have found this shell in one or two localities near 
here, and also at Lindfield. 
Planorbis corneus. Found this shell in great numbers, some years ago, 
in the mud thrown out of a “ rithe” at Bersted. Have never ascertained if 
it is to be found living there now, but have been told that there is a 
probability of its having been destroyed by an overflow of sea-water which 
occurred some time ago. 
Planorbis vortex. Found in some stagnant pools. 
Planorbis fontanus. Occurs in the mill-stream at Ratham. 
Planorbis nautileus. Found at Ratham and also at Wisboro’ Green. 
Planorbis albus. In stream at Ratham. 
Pisidium obtusale. At Burton, near Petworth. 
Unio pictorum. At Burton—Wuitu1am Jerrery (Ratham, Chichester).

“ Catal gue of Sussex Mollusca” was passing through the press, we have 
been enabled to incorporate most of the above additions.—Eb.]
